Discussion

  • mod_1: male and female weight data added
  • Males are assumed to differ from females by {p_Am} only
  • mod_3: v is reduced
  • mod_4: males have equal state variables at b, compared to females
  • mod_5: Pseudo-data point k is used, rather than k_J; Data set tp and parameter t_R are added, the latter replacing clutch interval t_N. Postnatal T is based on PrinPres1991, see get_T_Aves. See further the revision page, theme puberty
